I thought I would share this link since it relates to cellular phones.

I'm still guessing the phone pings have probably turned up nothing, otherwise I'm sure we'd see LE doing searches in other areas, even possibly other cities or states etc.
I had a what if theory also...
I read that DB followed the Anthony case, don't know the source of that but it was posted somewhere here on WS. Her cell phone was pinged also. You can go to google and search for Casey Anthony cell ping map and you will see the results.
What if whoever was responsible for Lisa's dissapearance was premeditating this crime and either destroyed the phones, or placed them in water right away? I can't image they were still pinging out of the neighborhood or like I said, we would probably see some other searches by LE being done.
I've also read up on how these pings work. From what I can tell, they only ping every so often (I believe in minutes). I wonder if that's why LE has been searching 34th & Brighton. Maybe the phone was only pinging at the house, then the last ping was near that intersection? I also know you can't pinpoint these phones by pings unless they are very sophisticated phones like iphones and such. If this is the case, I'm still leaning on everything being placed in the Missouri river.
Any ping experts in the house?
